Start with the files you have
A project begins as a folder on your computer, not an empty proprietary workspace. Your files remain portable, legible, and yours to move.
About Nebula Writer
We’re building AI for the work behind the document.
Nebula Writer is a local-first workspace that brings your files, formats, and AI assistance together—without taking judgment away from the person doing the work.
Our premise
The document is the output. The project is the context.
Your files
Begin with the material already on your computer.
Native formats
Work across documents, sheets, slides, and PDFs.
Visible changes
Review what AI proposes before it becomes final.
Why we are building it
The blank page is only a small part of the job.
Real projects are folders full of source material, drafts, data, citations, presentations, decisions, and revisions.
AI transformed software work by learning to understand a codebase, edit files, use tools, and show what changed. Document work deserves that same depth of context—not another chat box beside an empty editor.
Nebula Writer starts from the project rather than the prompt. It brings the files that shape an answer into one workspace, understands the document being edited, and keeps every consequential change visible to the author.
The goal is straightforward: help people move from scattered material to finished work without giving up control of their files, their reasoning, or their voice.
Our direction
Build an AI workspace that respects the craft behind the final document.
Understand the format
A spreadsheet, paper, report, and presentation each carry different structure. Good assistance should preserve that structure instead of flattening every task into chat.
Make changes reviewable
AI should show its work. Authors need to see what changed, keep what helps, reject what does not, and remain responsible for the final document.
Keep the workspace calm
Power does not need to look complicated. Files, editor, preview, and agent should work as one focused surface for getting to a finished result.
Who it is for
For work that gets better as context accumulates.
Nebula Writer is designed for people whose deliverables depend on more than the words in the current draft.
Research
Researchers and students
Bring papers, references, notes, LaTeX source, and revisions into one project context.
Writing
Writers and editors
Move from source material to drafts, review passes, and publishable documents without losing your voice.
Operations
Analysts and knowledge teams
Connect reports to the spreadsheets, PDFs, presentations, and decisions behind them.
